5. The change in height reading is live as long as the button is held. Wait until the height
reading has settled to a stable value and record this reading.
6. Average three readings. The acceptable average change in height should be from 20 to 50
mm.
7. If the average is less, increase the DZ setting with the buttons. If the average is
more, decrease the DZ setting with the buttons.
8. Repeat Steps 3 to 7 until the average falls within 20 to 50 mm.
Manual Gain Calibration:
This test will drive the boom at full speed in the selected direction for one second. Make sure
the boom has full range of movement.
The purpose of this test is to determine the sprayer boom speeds. It is recommended that
each test is performed three times and the readings averaged. From the speed measurements
taken, use Table 1 to determine the appropriate gain values to use for each function.
1. Follow Section 5.2 Step 1 (level booms, working RPM, etc.) before proceeding.
2. Choose the gain up or down setting (Figure 2).
3. Press and hold the button.
4. The valve will turn on at 100 percent speed for exactly one-second, regardless of the value
of the gain setting. The screen will show the actual change in height.
5. The change in height reading is live as long as the button is held. Wait until the height
reading has settled to a stable value and record this reading. This is the boom speed in
inches per second (in/s) or mm per second (mm/s).
6. Repeat Steps 3 to 5 three times, repositioning the boom as necessary. Average the three
readings.
7. Set the gain value using the buttons using Table 1 below as a guideline.
